-Your First Application Using PySide2 and QtQuick/QML
-*****************************************************
-
-QML is a declarative language that lets you develop applications
-faster than with traditional languages. It is ideal for designing the
-UI of your application because of its declarative nature. In QML, a
-user interface is specified as a tree of objects with properties. In
-this tutorial, we will show how to make a simple "Hello World"
-application with PySide2 and QML.
-
-A PySide2/QML application consists, at least, of two different files -
-a file with the QML description of the user interface, and a python file
-that loads the QML file. To make things easier, let's save both files in
-the same directory.
-
-Here is a simple QML file called `view.qml`:
-::
- import QtQuick 2.0
-
- Rectangle {
- width: 200
- height: 200
- color: "green"
-
- Text {
- text: "Hello World"
- anchors.centerIn: parent
- }
- }
-
-We start by importing `QtQuick 2.0`, which is a QML module.
-
-The rest of the QML code is pretty straightforward for those who
-have previously used HTML or XML files. Basically, we are creating
-a green rectangle with the size `200*200`, and adding a Text element
-that reads "Hello World". The code `anchors.centerIn: parent` makes
-the text appear centered in relation to its immediate parent, which
-is the Rectangle in this case.
-
-Now, let's see how the code looks on the PySide2.
-Let's call it `main.py`:
-::
- from PySide2.QtWidgets import QApplication
- from PySide2.QtQuick import QQuickView
- from PySide2.QtCore import QUrl
-
- app = QApplication([])
- view = QQuickView()
- url = QUrl("view.qml")
-
- view.setSource(url)
- view.show()
- app.exec_()
-
-If you are already familiar with PySide2 and have followed our
-tutorials, you have already seen much of this code.
-The only novelties are that you must `import QtQuick` and set the
-source of the `QQuickView` object to the URL of your QML file.
-Then, as any Qt widget, you call `QQuickView.show()`.
-
-.. note:: If you are programming for desktop, you should consider
- adding `view.setResizeMode(QQuickView.SizeRootObjectToView)`
- before showing the view.
